Nicole "Snooki" Polizzi gave birth to her first child at a hospital in Livingston, N.J. on Sunday, the reality star's rep said.
"The world just got another Guido!!!" Snooki's rep told MTV.
"Lorenzo Dominic LaValle has entered the world weighing 6 pounds, 5 ounces. Nicole, Jionni and Enzo are doing great!"
The reality star first broke the news of her pregnancy in March, along with the announcement of her engagement to LaValle.
The pregnancy was partly documented in "Jersey Shore" and its spinoff, "Snooki & JWoww," MTV reported.
